Researchers have identified specific metabolites that can be used as biomarkers for distinguishing dengue and Chikungunya infections.

Currently, antigen-based diagnostic tool is available for dengue and anti-body based diagnostic tool is available for chikungunya.

Antigen-based and Anti-body based tools takes time for diagnosis.

The metabolite clusters can be used for various applications such as

Biomarkers

Studying disease progression

Evaluating potential of drugs

Disease Management

Indigenously Developed SONARS

In News: The Government has formally inducted four types of indigenously developed SONARS that will boost its underwater surveillance capability recently.

NAVAL Systems

Recently, Kochi based Naval Physical Oceanographic Laboratory (NPOL) of DRDO, has handed over the following four naval systems to Indian Navy.

Induction of these Systems will increase the underwater surveillance capability of Indian Naval ships.

All these Systems are to be productionised in India.

ABHAY

Abhay (Compact Hull-Mounted Sonar for Small Ships & Shallow Water Crafts): Induction of Abhay (by replacing the vintage Russian sonar) enables indigenous sonar system to be installed on small ships, thereby enhancing the ASW surveillance capability of the fleet to smaller vessel, like Shallows Water Crafts, Light Frigates & Patrol Vessels, which was hitherto limited to frigates and destroyers.

HUMSA-UG

HUMSA-UG (Upgrade for the Hull-Mounted Sonar Array (HUMSA) Series of Sonar Systems for Ships): It enables smooth upgrade of the capabilities of the indigenously-developed legacy Sonar System HUMSA, by drastically minimizing the existing hardware and addressing technology obsolescence issues, which is currently operational on-board on 18 ships.

NACS

NACS (Near-field Acoustic Characterization System (NACS) for Ship Sonars): It provides a simple and operationally efficient means to determine the frequency-dependent 3-D transmission and reception characteristics of the hull-mounted sonar aiding in the optimum performance and maintenance of the sonar.

AIDSS

AIDSS (Advanced Indigenous Distress Sonar System (AIDSS) for Submarines): It is used to signal that a submarine is in distress and thereby enable quick rescue and salvage.

It is a life-saving alarm system designed to transmit sonar signals of pre-designated frequency and pulse shape in an emergency situation, so as to attract the attention of Rescue Vessel in the vicinity.

Trojan Asteroids

Trojans are asteroids that are constant companions to planets in our solar system as they orbit the Sun and they constantly lead or follow in the same orbit, they will never collide with their companion planet.
